WATER-WHEEL.

Specification of Letters Patent No. 32,131, dated April 23, 1861.

To all whom it may concern:

Be it known that I, CHARLES GREENAW LT, of Seiberlingville, in the county of Lehlgh and State of Pennsylvania, have invented an Improvement in W ater-WVheels; and I declare that the following is a full, clear, and exact description of the principle or character which distinguishes it.from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which Figure l is a plan of the wheel; Fig. 2 a side elevation of the wheel with part of the casing removed to show the buckets, and Fig. 3 a view of the separate hub piece.

My improvement consists in certain improvements in water wheels described as follows:

Fig. 1 is a plan of the wheel and Fig. 2

is a side elevation of the wheel with part of the casing removed to show the buckets. The wheel is shown in Fig. 2, in the position in which it is used, the water entering from be-,

low and escaping at the periphery near the upper part. The position being assumed that a multiplication of reacting surfaces are an offset m which is made by agradual thickening of the back of the bucket toward the outlet, this thickening as 00 being shown in Fig. 2, which terminates somewhat abruptly at the outlet. The object of this drop or offset is to remove any resistance to the delivery of the water from the back of the bucket in advance of the outlet and to give the water a free drop as it were at that point. As it often happens in country 10- calities that wooden shafts are the most convenient to use for these water wheels I adapt my wheel to be used with either a wooden or iron shaft. For this purpose I cast a hexagonal hub n separate from the wheel fitting the opening it in the wheel and this hub has a central bore for the reception of an iron shaft when that is to be used. This hub is removed when a wooden shaft is to be used and the opening it is of the proper size for this kind of shaft.

What I claim as my improvement in reaction tub wheels is- 1. The use and arrangement of the half buckets e in the manner set forth.

2. The offset m when used with the buckets a, a, arranged and operating as herein set forth.
